It might just be that my babies are just different to each other but ds used to do a yellow poo at least once daily. but dd only poos every 4 days or so and it's always a dark brown colour. Completely different consistency too. Sorry for tmi. Is it maybe because i'm taking iron? I am tempted to stop taking it to see if it makes a difference. I don't want her to be uncomfortable because she's constipated.
Should add that she seems happy and healthy enough if a bit windy.
